VTE-XXX-XXX-5-12 extra energy efficient thyristor exciter for low-voltage synchronous motors of generally application electric drive (mill, pumps, e.t.c.).  Only well-known brands components used in the production.VTE-xxx-xxx-5-12 Extra energy efficient PLC-controlled low voltage synchronous motors excitation device for generally application electric drive (mill, pumps, e.t.c.). 100% reservation of thyristors rectifiers (two rectifiers). Excitation powered from built-in transformer. This model contain built-in power panel for Stator control. Only well-known brands components used in the production. 

Features:
  
  1. PLC-controlled
  2. Built-in power panel (control key [START/STOP], motor protection AC-breaker, motor AC-vacuum contactor) for commutation of stator of the motor
  3. 100% thyristors (bridges) rectifiers reservation.
  4. Two bridges 3-phase thyristors rectifier, automatically  reservation and switched for best power factor
  5. Built-in transformer UNICORE-technology (no-load current less 0.3A) with two-tapping of secondary winding
  6. IDLE-AC contactor with magnetic latch ( not require power for hold) switch-off transformer automatically for idle-time bridges thyristors rectifier
  7. Sided maintenance 
  8. Small footprint 
Application:     
  1. Generally application (mill, pump e.t.c) 
  2. Upgrade old existing excitation system for energy saving and industrial control integration
  3. Hig-h and Low-voltage synchronous motor excitation

Cases

1.Power saving function by automatically power factor correction  
2.UNICORE transformer: No-load current less 0,3A  
3.Idle AC-contactor with magnetic latch. No power in the ON-state. Switches off the transformer in the absence of excitation.  
4.Cooperation rectifiers and transformers with two taps. After the forcing, the main rectifier is connected to the tap of low voltage, so the angle of thyristor control near the minimum, and nearly sinusoidal voltage waveform. As a result of decreasing the iron loss transformer.

Reservation rectifier
When a fault is detected thyristors control-channel (delayed conduction or no conduction) main rectifier operation is automatically switched to the forcing-rectifier.
If the fault persists, the exciter continues to work on forcing-rectifier to a scheduled stop. If the fault occurs on the forcing-rectifier, the engine and exciter to switched off.

Package:
1. Exciter VTE-XXX-XXX-5-12
2. User manual
3. CD-disk Ajuster software
4. USB A-B cable

Data Logger. Oscilloscope
The digital PLC-control system is provided by the data logger. In the non-volatile memory 31 are stored waveform of events: starts/stops the engine, on/off the power of control system.
Statistical information in the history:
- Total operating time of the control system and the engine
- Quantity of emergency shutdowns of the engine (counters for each type of accident)

Advanced oscilloscope unit 

View waveforms from data logger and statistics possible with Ajuster software (reading data by USB interface) and operator panel (Linux-based, color TFT display with touch-screen). Operator panel, provides extended service for data logging:
  1. Storage waveforms and statistics on the SD-card (can be removed)
  2. Waveform - a continuous record of 30 days (ring-record)
  3. Waveform, and statistics can be copied to USB flash-drive
  4. SSH access to files is available via Ethernet
  5. Using the operator panel, can view the waveform of any event, within an arbitrarily given time interval
